Symfony3 无法使用服务中的路由器创建已翻译的路由

Question

我正在尝试在我的主导航中构建一个语言切换器，它是由 KNPMenuBundle. Translations are done with the JMSTranslationBundle 创建的。两者都很好。

我想用我的菜单生成器创建一个语言切换器，但是正确路由的生成让我有些头疼。

这是我的服务：

class MenuService
{
    private $factory;
    private $translator;
    private $router;

    public function __construct(FactoryInterface $factory, Translator $translator, Router $router)
    {
        $this->factory = $factory;
        $this->translator = $translator;
        $this->router = $router;
    }

    public function createMainMenu(RequestStack $requestStack, array $languages)
    {
        // Language Switcher - $languages === ['en', 'de']
        $request = $requestStack->getCurrentRequest();
        $routeName = $request->get('_route');

        $menu->addChild('menu.language', array(
            'uri' => '#',
            'label' => '<i class=\'fa fa-flag-checkered\'></i> '.$this->translator->trans('menu.language.main'),
            'extras' => array('safe_label' => true)
        ))
            ->setAttribute('class', 'dropdown singleDrop')
            ->setChildrenAttribute('class', 'dropdown-menu dropdown-menu-left')
        ;

        foreach ($languages as $language)
        {
            $menu->getChild('menu.language')->addChild('menu.language.'.$language, array(
                'route' => $this->router->generate($routeName, array_merge($request->get('_route_params'), ['_locale' => $language]))
            ));
        }
    }

这是我的服务定义

menu_builder:
    class: AppBundle\DependencyInjection\MenuService
    arguments: ['@knp_menu.factory', '@translator.default', '@jms_i18n_routing.router']

menu.main:
    class: Knp\Menu\MenuItem
    factory: ['@menu_builder', createMainMenu]
    arguments: ['@request_stack', '%locales%']
    scope: request
    tags:
      - { name: knp_menu.menu, alias: main }

如果我注入 JMSTranslationBundle 提供的路由器，我会收到以下错误：

An exception has been thrown during the rendering of a template ("Unable to generate a URL for the named route "/en/" as such route does not exist.").

如果我使用的是 symfony 的默认路由器，我会收到此错误消息：

An exception has been thrown during the rendering of a template ("Unable to generate a URL for the named route "homepage" as such route does not exist.").

当我在控制台调试路由器时，这是输出：

  en__RG__homepage                                         ANY        ANY      ANY    /en/                                                 
  de__RG__homepage                                         ANY        ANY      ANY    /de/

必须使用哪个路由器才能使路由正常工作？

Answer 1

我发现我在使用这两个包时犯了错误。

JMS\I18nRoutingBundle\Router::generate() 函数将 return 绝对路径 给函数的路由。

所以会发生以下情况：

$absolutePath = $this->router->generate('homepage', array_merge($request->get('_route_params'), ['_locale' => $language]));
dump($absolutePath); // Will return "/de/" or "/en" in my case

所以，考虑到这一点，我用参数 route 生成的路由显然会失败，因为函数不 return route 但 absolute path.

鉴于此，这有效：

foreach ($languages as $language)
{
    $menu->getChild('menu.language')->addChild('menu.language.'.$language, array(
        'uri' => $this->router->generate($routeName, array_merge($request->get('_route_params'), ['_locale' => $language]))
    ));
}

如果我将 route 更改为 uri，我的代码将正常工作。
